Système Magique Cordial

Système Magique Cordial refers to two historical magical girl organizations. First, a league of magical girl nobility in Europe[1] which developed during the relatively peaceful years after the Napoleonic Wars and which collapsed during WWI. Second, the most successful MSY rival, which developed in the latter half of the 21st century, and which finally agreed to unification with the MSY (after being assured major concessions) in 2210 following a near quarter-century of cold war.
